Randomized Controlled Trials of Mindfulness and Acceptance-Based Interventions Over the Past Two Decades: A Bibliometric Analysis

Prevalence and 20-year trends in meditation, yoga, guided imagery and progressive relaxation use among US adults from 2002 to 2022

Meditation, yoga, guided imagery, and progressive relaxation are promoted as complementary approaches for health and wellbeing in the United States, but their uptake by different sociodemographic groups is unclear. This study assessed the prevalence and 20 year trends in the use of these practices in US adults between 2002-2022. We examined practice use and associations with sociodemographic and health factors in a population-weighted analysis of n = 134,959 participants across 5 cycles of the National Health Interview Survey. The overall use of meditation (18.3%, 60.53 million), yoga (16.8%, 55.78 million) and guided imagery/progressive relaxation (6.7%, 22.22 million) increased significantly from 2002 to 2022. Growth was consistent across most sociodemographic and health strata, however users of 'Other' race (comprising 54% Indigenous Americans, Odds Ratios; ORs = 1.28-1.70) and users with moderate (ORs = 1.19-1.29) psychological distress were overrepresented across all practices, and those with severe psychological distress were overrepresented in meditation (OR = 1.33) and guided imagery/progressive relaxation (OR = 1.42). Meditation use has accelerated over time for 65 + year olds (OR = 4.22), people not accessing mental health care (OR = 1.39), and less educated (OR = 4.02) groups, potentially reflecting unmet health needs. Health professionals should consider the extensive use of complementary practices in service and treatment planning and consider their risks and benefits.

Mindfulness-based therapies for cancer patients and families: a systematic review

BACKGROUND

Mindfulness-based therapies (MBTs) addressed to patients with cancer have been widely studied in the last two decades, and their efficacy has been systematically reviewed and meta-analysed. Although findings from literature highlight benefits of MBTs on several patients' health outcomes, these should be appraised taking into consideration the characteristics of the selected studies. In this systematic review, we summarised the current evidence of the efficacy of MBTs in improving the quality of life of both patients with cancer and their relatives, with a focus on the methodological quality, type of MBT evaluated and population involved in existing randomised controlled trials (RCTs).

METHODS

We searched English language articles published until February 2021. Couples of authors independently applied inclusion criteria and extracted findings. Thirty RCTs were included.

RESULTS

Nearly half of the studies were performed in English-speaking countries outside of Europe, with females diagnosed with breast cancer. Most considered heterogeneous phases of illness; one study only was performed on relatives. In most cases, different measures were employed to evaluate the same outcome. The efficacy of MBTs has been demonstrated in 25 of the 30 included articles. The methodological quality of RCTs was acceptable.

CONCLUSION

The heterogeneity of studies' characteristics makes findings on the efficacy of MBTs poorly informative with reference to different clinical and cancer-related psychological conditions. Studies on more homogeneous samples by cancer site and phase, as well as performed in different cultural contexts, could provide a basis for better evaluating and targeting MBTs' protocols for the specific needs of patients with cancer and their relatives.

Cognitive Behavioural Therapies for Weight-Loss in Adults: A Scoping Review Protocol

Obesity and being overweight are very important public health issues due to their increasing prevalence worldwide. Third-wave cognitive behavioural therapies (3wCBT) have emerged in the last few years to promote weight loss. However, the scientific evidence identifying the most commonly used 3wCBT in weight-loss interventions in adults is still needed. The objective of this scoping review will be to identify the most widely researched 3wCBT used to facilitate weight loss in an adult population who are overweight and obese, according to the published scientific literature. The search will be carried out independently by two authors in PubMed (MEDLINE), Scopus, EMBASE, Web of Science, and PsycINFO, using search equations that contain keywords related to our search question: (1) population: adult and elderly population, (2) intervention: terms related to 3wCBT, and (3) results: weight loss or weight management. The data extraction will be performed following the indications of the Cochrane manual, and the results will be presented in three tables. The 3wCBTs have shown promising results for weight loss, but it is not yet known which of them is the most widely used to achieve weight loss in the adult population. Thus, the results of this scoping review could guide professionals in the psychological treatment of obesity and being overweight.

Dismantling the Component-Specific Effects of Yogic Breathing: Feasibility of a Fully Remote Three-Arm RCT with Virtual Laboratory Visits and Wearable Physiology

Despite the growing research base examining the benefits and physiological mechanisms of slow-paced breathing (SPB), mindfulness (M), and their combination (as yogic breathing, SPB + M), no studies have directly compared these in a "dismantling" framework. To address this gap, we conducted a fully remote three-armed feasibility study with wearable devices and video-based laboratory visits. Eighteen healthy participants (age 18-30 years, 12 female) were randomized to one of three 8-week interventions: slow-paced breathing (SPB, N = 5), mindfulness (M, N = 6), or yogic breathing (SPB + M, N = 7). The participants began a 24-h heart rate recording with a chest-worn device prior to the first virtual laboratory visit, consisting of a 60-min intervention-specific training with guided practice and experimental stress induction using a Stroop test. The participants were then instructed to repeat their assigned intervention practice daily with a guided audio, while concurrently recording their heart rate data and completing a detailed practice log. The feasibility was determined using the rates of overall study completion (100%), daily practice adherence (73%), and the rate of fully analyzable data from virtual laboratory visits (92%). These results demonstrate feasibility for conducting larger trial studies with a similar fully remote framework, enhancing the ecological validity and sample size that could be possible with such research designs.

The Western origins of mindfulness therapy in ancient Rome

Stoic philosophy has multiple parallels with cognitive behavioural therapy interventions. In their ancient texts, the Roman Stoics present a set of theoretical principles and behavioural strategies that are directly relevant to the clinical care of patients with a wide range of neuropsychiatric conditions. Mindfulness is a key component of the 'third wave' of modern psychotherapy that closely resembles the ancient Stoic practice of attention or 'concentration on the present moment'. Stoic mindfulness draws attention to one of the main principles driving both Stoicism and modern psychotherapy: the assumption that cognitive activity (reasoning) mediates emotions and behaviours. This principle can be traced back to Epictetus' Enchiridion, where he recognises that 'men are disturbed not by things, but by the views which they take of things'. It has been shown that cognitive behavioural therapies and mindfulness-based interventions directed at patients with neuropsychiatric disorders were originally developed as Stoic-inspired treatment interventions. Both Albert Ellis and Aaron Beck (the founders of rational emotive behaviour therapy and cognitive behavioural therapy, respectively) explicitly acknowledged the role of Stoicism as the philosophical precursor of their treatment approaches. The effective implementation of evidence-based guidelines would benefit from an increased awareness of the influence of the Stoic tradition of philosophical therapy on the treatment approaches currently in use in neuropsychiatry.

Exploring the past, present, and future of the mindfulness field: A multitechnique bibliometric review

This paper provides an overview of the mindfulness literature up until the end of 2020 by (a) uncovering its underlying intellectual structure, (b) identifying the most influential and popular themes, and (c) presenting new directions for future research on mindfulness. To this end, a systematic quantitative review based on bibliometric methods was conducted, which is perhaps less prone to researcher bias and can complement existing meta-analyses and qualitative (narrative) structured reviews as an objective approach. Three bibliometric techniques—document co-citation analysis, co-word (co-occurrence and content) analysis, and bibliographic coupling—were applied to explore the past, present, and future of mindfulness research. The co-citation analysis showed that measurement, mechanisms, mindfulness-based interventions, and examinations of the efficacy of mindfulness interventions are among the key theoretical knowledge bases from which the field of mindfulness is derived. The content analysis demonstrated the beneficial effects of mindfulness meditation for physical and mental health conditions. The bibliographic coupling revealed novel directions in cognitive behavioral therapy, emotion regulation, the application of mindfulness practice to children and adolescents, mindfulness at work, and the role of mindfulness in positive psychology. The large sample of articles that was analyzed allowed us to provide a broader and more objective overview than possible with other forms of literature reviews. The combination of the three bibliometric techniques granted deeper insights into the complex multidisciplinary field of mindfulness, along with specific suggestions for future research.
